The document consists of two pages: the first page presents 20 addition problems for practice, while the second page provides the same set of problems along with their corresponding correct answers. This resource is designed to help students improve their speed and accuracy in performing multi-addend mental addition, which is a foundational skill in elementary arithmetic education. By providing both the exercise and the solution key, the worksheet facilitates self-assessment and guided learning for students working on their computational proficiency. The content is structured as a clear, repetitive set of exercises that encourages consistent daily practice in mental calculation techniques.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":20,"@type":76,"position":81},"https://docshare.wps.com/document/exam/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/grade-4-addition-worksheet-mental-math-adding-three-2-digit-numbers/545929/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/grade-4-addition-worksheet-mental-math-adding-three-2-digit-numbers/545929.png","ImageObject",300,407,{"name":92,"@type":93},"Ezra","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-06","2026-10-12",true,{"@type":102,"interactionType":103,"userInteractionCount":24},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What is the target grade level for this worksheet?","Question",{"text":112,"@type":113},"This worksheet is designed for Grade 4 students.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"What specific math skill is being practiced?",{"text":117,"@type":113},"The worksheet focuses on mental math, specifically adding three 2-digit numbers together.",{"name":119,"@type":110,"acceptedAnswer":120},"Are the answers provided in the document?",{"text":121,"@type":113},"Yes, the second page of the document includes an answer key for all 20 problems listed.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},545929,1791775770,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":19,"category_name":20,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":24,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":14,"language":139,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":67,"update_tm":129,"read_time":24,"preview_page_count":4},1099514068035,"https://ap-avatar.wpscdn.com/davatar_276721f389ce27ea32af1340a28f341c","Mental math: adding three 2-digit numbers   \nGrade 4 Addition Worksheet  \nFind the sum.  \n1. 82 + 80 + 93 =   2. 92 + 54 + 53 =   3. 85 + 28 + 58 =   4. 45 + 70 + 74 =   5. 12 + 12 + 25 =   6. 52 + 46 + 47 =   7. 76 + 74 + 92 =   8. 44 + 18 + 35 =   9. 97 + 65 + 46 =   10. 78 + 29 + 30 =   11. 57 + 12 + 73 =   12. 17 + 80 + 98 =   13. 26 + 33 + 65 =   14. 56 + 63 + 65 =   15. 56 + 92 + 38 =   16. 37 + 50 + 20 =   17. 34 + 71 + 55 =   18. 63 + 37 + 35 =    \n19. 65 + 28 + 70 =   20. 51 + 73 + 84 =    \nMental math: adding three 2-digit numbers   \nGrade 4 Addition Worksheet  \nFind the sum.  \n1. 82 + 80 + 93 =  255  2. 92 + 54 + 53 =  199   \n3. 85 + 28 + 58 =  171  4. 45 + 70 + 74 =  189   \n5. 12 + 12 + 25 =  49  6. 52 + 46 + 47 =  145   \n7. 76 + 74 + 92 =  242  8. 44 + 18 + 35 =  97   \n9. 97 + 65 + 46 =  208  10. 78 + 29 + 30 =  137   \n11. 57 + 12 + 73 =  142  12. 17 + 80 + 98 =  195   \n13. 26 + 33 + 65 =  124  14. 56 + 63 + 65 =  184   \n15. 56 + 92 + 38 =  186  16. 37 + 50 + 20 =  107   \n17. 34 + 71 + 55 =  160  18. 63 + 37 + 35 =  135   \n19. 65 + 28 + 70 =  163  20. 51 + 73 + 84 =  208","cbCaiqwkKEPBwpnE","https://ap.wps.com/l/cbCaiqwkKEPBwpnE","pdf",13370,"English","# Mental Math Addition Practice\n## Worksheet Exercises\n## Answer Key","[{\"question\":\"What is the target grade level for this worksheet?\",\"answer\":\"This worksheet is designed for Grade 4 students.\"},{\"question\":\"What specific math skill is being practiced?\",\"answer\":\"The worksheet focuses on mental math, specifically adding three 2-digit numbers together.\"},{\"question\":\"Are the answers provided in the document?\",\"answer\":\"Yes, the second page of the document includes an answer key for all 20 problems listed.\"}]","Grade 4 Addition Worksheet - Mental Math - Adding Three 2-Digit Numbers | PDF"]
